Hi Justin,

The deliveries on this mailing list have been delayed, so we already 
figured out a solution. Thanks anyway for your analysis and suggestions.

Since it is an important question about programming basics, the 
professor didn't want to skip this problem.

The due date was already in the past, so we manually corrected the 
grades for the affected students while keeping an eye on the automated 
grading status of the other parts.
